Title: Bus differential relay
Inventor: SALOWE SEYMOUR
IPC: H02H7/22
Filed: 1986-09-05
Granted: 1991-08-20
Abstract: ABSTRACT OF THE DISCLOSURE           A bus differential relay which is capable of distinguishing between an internal bus fault and an external fault on a feeder line with saturation of the faulted feeder line current transformer during portions of the alternating current cycles thereof is disclosed.   The relay generates a net current signal or differential signal from the signals generated by the feeder line current transformers of the protected bus section.   During an internal fault,  the current differential signal extends in amplitude beyond fault current limits  and a  trip  signal  is  generated to interrupt current to the bus section.    During an external fault with current transformer saturation, the current differential signal will include ampli-tude portions of the alternating current cycles which exceed the  fault  limits.     However,   the  current differential signal will also include portions of its waveform which are  zero or near zero in amplitude (flat spots) which portions reflect that the current transformer of the faulted feeder line is operating out of saturation.   If these flat spots occur for a sustained duration of time,  or each half cycle the trip signal generation by the relay is inhibited.

Abstract: APPARATUS AND PROCESS FOR OXYGENATION OF LIQUID STATE DISSOLVED OXYGEN-CARRYING FORMULATION   Abstract of the Disclosure Perfluorocarbon emulsion formulations are oxygenated prior to use by means of a portable oxygenation system. The blood substitute is in a closed container or bag.  An oxygen-containing gas is introduced into the bag from a separate container.  The bag is continuously agitated for a sufficient time to increase the PO2 Of the perfluorocarbon emulsion formulations to a desired pressure, e.g., to at least 600 mmHg.   In one embodiment, the system used for oxygenation of the perfluorocarbon emulsion formulations comprises a small tank for gas having an inlet port and an outlet port fitted with shut-off valves.  The outlet port is adapted to be connected to a filter which, in turn, is adapted to be connected to the inlet port of a three-way valve.   The primary outlet of the three-way valve is adapted to mount a hypodermic needle which is adapted to be pushed through a rubber septum in a port of the bag to communicate with the interior of the bag.   The tank is adapted to be filled with oxygen-containing gas, such as carbogen, from a main gas source under pressure.  The tank, filter,  three-way valve and needle arrangement are connected in series,  and the oxygen-containing gas is permitted to flow from the tank into the bag holding the emulsion formulation.  After the gas is introduced into the bag,  the three-way valve is closed to prevent leakage of the gas from the container.  The container is then agitated to oxygenate the emulsion formulation.

Title: Magnetic recording material
Inventor: MOSKOVITS MARTIN
IPC: G11B5/84
Filed: 1987-10-02
Granted: 1993-05-18
Abstract: ABSTRACT OF THE DISCLOSURE           The invention provides a process for preparing magnetic recording material by depositing ferromagnetic material in particulate form into an aluminum substrate.  The aluminum substrate is prepared by cleaning an aluminum or aluminum metal containing substrate; anodizing the cleaned metal substrate, to produce a suitably pitted or porous oxide substrate surface; and rinsing the anodized substrate, substantially to remove therefrom acid residues remaining from the anodizing step.  The substrate in contact with a liquid solution of a salt of at least one ferromagnetic metal is then subjected to electrolysis with alternating current, to deposit the metal into the pores of the oxide in small-particle, ferromagnetic form while adjusting and controlling the frequency of the alternating current to obtain discrete particles in the pores assembled in an anisotropic configuration.  Excess liquid solution is subsequently removed from the so-treated substrate.  The material is then preferably coated with a suitable resin or polymer to seal the pores and then polished to generate a suitable surface for reading or writing by magnetic heads.
